ODF3B affects the proliferation and apoptosis of glioma via the JAK/STAT pathway.

The pathogenesis of glioma has remained unclear. In this study, it was found that high expression of the outer dense fibers of sperm tail 3B (ODF3B) in gliomas was positively correlated with the grade of glioma. The higher the grade, the worse the prognosis. ODF3B is closely related to the growth and apoptosis of glioma. In terms of mechanism, ODF3B was found to affect the proliferation and apoptosis of glioma through the JAK1 and JAK2/STAT3 pathways. ODF3B was also found to affect the growth and apoptosis of glioma in vivo. We conclude that ODF3B affects glioma proliferation and apoptosis via the JAK/STAT pathway and is a potential therapeutic target.

Extracranial multiorgan metastasis from primary glioblastoma: A case report.

BACKGROUND: Glioblastoma has a high degree of malignancy and poor prognosis. It is common to have in situ recurrence and intracranial metastasis, while extracranial metastasis is rare, and extracranial multiorgan metastasis is extremely rare. We report a case of glioblastoma with extracranial multiorgan metastasis, which will strengthen clinicians' attention to the extracranial metastasis of glioblastoma and its treatment. CASE SUMMARY: A male patient visited our hospital for treatment of dizziness and headache. Magnetic resonance imaging of the brain revealed a space-occupying lesion in the right temporoparietal occipital region. Chest computed tomography and abdominal ultrasound were normal, and no space-occupying lesions were observed in other organs of the body. The patient underwent surgery and diagnosed with glioblastoma. Postoperative concurrent radiotherapy and chemotherapy were completed. During the follow-up, the tumor was found to have metastasized to the scalp and neck, and a second tumor resection was performed. Postoperative follow-up revealed extracranial metastases to multiple extracranial organs including skull, scalp, ribs, spine, liver and lung. His family members refused further treatment, and requested only symptomatic treatment such as pain relief, and the patient died of systemic multiple organ failure. Survival time from diagnosis to death was 13 mo and from extracranial metastasis to death was 6 mo. CONCLUSION: Glioblastoma extracranial metastasis is extremely rare, clinicians should always pay attention to its existence. The mechanism of glioblastoma extracranial metastasis is still unclear, and genetic and molecular studies are required.
